Expert Solution
Concept and Principle:
  • The crystalline structure of a crystal is capable of diffracting incident X-rays in different directions. This is known as X-ray diffraction.

 

  • Bragg’s law is used to explain the interference pattern of X-rays scattered by the crystals. As Bragg’s law the maximum intensity occurs when,

2dsinθ=mλ

Here d is the spacing between the crystals, θ is the grazing angle, m is the order, and λ is the wavelength.
